The image is actually there, however it's just some defect on the sensor in the Rover's camera (probably a speck of dust). You can prove this by noting that the same image appears in the same position in each individual image that makes up the stitched image.

An unidentified flying object (UFO) was caught in a NASA photo and not just any photo but the Billion Pixel View of Mars taken by Curiosity rover. Streetcap1 of Youtube detected and reported on it today. This objects looks to have a head in front on the left side and long wings bent down below it, causing it to appear much like eagles on Earth. If life is on Mars, we can assume there are many kind including predators that hunt from the air. This very well could be an eagle or even an alien craft...but we need a close up of the object with a better focus. It looks like a billion pixels still has a lot of things out of focus...is it NASA or is it something else? SCW

If you spend any time on "UFO Sightings Daily" you quickly realize that its owner, Scott Warring, identifies most rocks, shadows, and anything he cant identify as UFOs or aliens.I used to visit his site for the laughs but after a while it just gets kind of sad. He believes what he post.

JPEG compression artifacts can be very interesting they can lead to misconceptions by the unsophisticated viewer . . there are many examples regarding Mars . . . for example below . . .

This isn't really a JPEG thing thought, that just gives it slightly more interesting shape. The real issue is that there's a camera defect that creates this same little image in the same spot each time.

Experts say the four "objects" are actually just dead pixels in the rover's CCD camera — single points in the camera's imager that have lost functionality and register as white. Marc D'Antonio, a photo and video analyst for MUFON [Mutual UFO Network], told Huffington Post, "I fully concur at this point that these are dead pixels on the imager. All CCD [cameras] have them, and in a bland atmosphere like that at Mars, they would be very obvious as opposed to an active atmosphere like Earth, where they could end up hidden for a long time before anyone noticed them."

And as it relates to the issue of bad pixels...

Scientists with the Space Telescope Science Institute have even produced tables/maps of bad pixels on the Hubble Telescope's WFC3/IR camera.

In a way, it's somewhat humorous, perhaps even "cute"...like when a child asks an innocent question about "the Tooth Fairy".

But, the age of the Internet allows a very diverse, and heretofore unknown segment of the truly mentally deluded access to post their nonsense...and, of course, some tend to then "follow" them. Staying on the topic of Mars, and this thread...I don't know if it's worth sharing, and giving these videos extra "views", but...maybe so, just in case not everyone has seen them, as examples of a very, very mentally disturbed individual: YouTube name "Dave Stacey".

Again, just two examples. And, noting that either originally, or due to many negative responses, these videos cannot be commented on, and "Ratings have been disabled".

Yet, 5 years on, they still are available to view, on YouTube.

"Dave Stacey" presents a wonderful avatar, on this YouTube Channel...but, well. I am just dumbfounded, sometimes.

Is this serious? I am under the impression it is in jest. Personally i do not see tiny anything in the photos. If indeed this is real there is a great collaborator for Scott Waring waiting out there to find other non existent items in Martian photographs. Funny this post does not see tiny cryogenic squirrels? Also makes no mention of the numerous destroyed statues of various alien species who once ruled the red planet. Maybe someone can point out where exactly the tiny humans and apes are in the photos? There is a remote possibility thAt there indeed could be such organisms living on CO2!

May I ask, "Skaredstiff", if you are referring to my post just above, or to the OP of this thread?

Your post. I can not see what the poster references as tiny humans? Possibly the YouTube video lacks resolution to reveal what Dave thinks he sees. As far as the premise if the thread I am impressed with the very thoughtful and well presented demonstration if what appears to be exactly what is seen. Dead pixels.

I am sorry to have started what appears to be a "firestorm" of sorts. I was more interested in a discussion about the ability of people to infer what is actually a form of pareidolia, and then attempt to pass off that particular mental illusion/delusion as a so-called "fact".

Yes -- the affected instrument is Mastcam Right and the problem was obviously present before the rover even left Earth. The anomaly -- whether it's a foreign body on the camera or one of its filters, or a physical defect with the cameras CCD itself, can be seen in images that were taken on Sol 3 when they first deployed the mast. It appears no less than 75 times on the horizon in the recent panorama that NASA posted. The colouration of the defect is not typical of hot/dead pixel data, or JPG compression, which has me leaning towards the belief that it's a foreign body of some kind on the hardware. It looks like NASA might need to review their compliance to ISO cleanroom standards.

Sadly, Mr. Waring still believes that it is a bird. Well handled, Mick!
